6.1.4.3 CA NetSpy TCP/IP Interface

The CA NetSpy TCP/IP Interface records volume, performance,
and reliability data that is derived from the Management
Information Blocks (MIBs). CA NetSpy uses Simple Network
Management Protocol (SNMP) interface to read the MIBs that
are associated with the stack, and all the UDP, IF, TCP
interfaces.

Information may be collected for one or more TCP/IP servers.
TCPIPMON=YES/NO controls the monitoring of TCP/IP stacks and
SNMPHOST controls the logging of the TCP/IP related subtypes.

Information supplied by the CA NetSpy TCP/IP interface
includes the following data types:

o  TCP Connection (Subtype I)
   --------------------------
   Telnet data includes activity for each telnet session
   monitored during the installation defined interval.  The
   information for telnet session includes bytes sent and
   received counts, retransmission counts, acknowledgements,
   roundtrip time, etc.

o  TCP/IP Stack (Subtype J)
   ------------------------
   TCP/IP stack data includes activity for each TCP/IP server
   monitored during the installation defined interval.  The
   information for TCP/IP stack includes connection counts
   (active, passive, and failed), retransmission time,
   receive and send buffer sizes, etc.
